Computer programs

Procedures available in statistical packages presently on the market are not systematically reviewed here, because the task would be beyond the scope of the present book and the information would rapidly become obsolete. Sources of information about computer programs are given in Section 1.3. However, because ecologists are often not very familiar with series analysis, some information about the main commercial computer packages that offer programs for time series analysis is assembled in Table 12.9. In addition, three university-based packages are mentioned because they are the only ones, for the time being, that offer programs for some of the methods discussed in the previous sections. Information in Table 12.9 is not exhaustive. It was up-to-date at the time this book was completed (1998), but new software rapidly appears on the market.

*** The PASSTEC package is distributed by F. Ibanez and M. Étienne, Observatoire Océanologique, Station Zoologique, B.P. 28, F-06230 Villefranche-sur-Mer, France. PASSTEC means: Programme d'Analyse des Séries Spatio-Temporelles en Écologie Côtière.

**** The Interactive Time Series Modelling package is provided on diskettes with the book of Brockwell & Davis (1991b). This book briefly describes the theory and gives examples of how to use the programs. It was designed as companion to the book of Brockwell & Davis (1991a).
